old Crane boiler info

Hello. I have an old Crane boiler in a 4-unit apt. building.
On the front it says #1 sectional boiler, cat# 1-8,
series B-A. It looks like it was once a coal burner, converted to oil. Someone had removed the bottom door, and cemented a beckett flame retention head oil burner in place. It also says protected by patents 1856334 1887760 1898096 1900947 1939350 1964074. Does anyone have any information about this boiler? How old it might be? Its efficiency? I'm debating whether to replace it. send replies to *****

Overall efficiency of converting the potential heat in the fuel oil to usable heat in the apartments is probably less than 50%, maybe as low as 30% depending on several unknown factors concerning the building and the distribution system.
